COMBINED TRAP, WASTE, AND OVER/FLOW.

Specification of Letters Patent.

Patented Nov. 10, 1908.

- Application filed June 27, 1907. Serial No. 381,082.

To all whom it may concern:

Be it known that I, JOSEPH P. HEENEY, a citizen of the United States,iesiding at East St. Louis, in the county of St. Clair and State ofIllinois, have invented certain new and useful Improvements in aCombined Trap, aste, and Overflow, of which the following is aspecification.

My invention relates to that class of basin and tub fittings comprisinga combined trap, waste and overflow valve.

The main object of the invention is to provide a simple and eifectivetrap, waste and overflow in which the valve cannot be held permanentlylocked to its seat. This object I accomplish by means of the construction shown in the accompanying drawings, in which Figure 1 is avertical sectional view of one form of my trap, waste and overflowvalve. Fig. 2 is a similar view of another form thereof. Fig. 2 is adetail plan of the valve proper of Fig. 2. Fig. 3 is a view similar toFig. 1 of a third form of my improved trap, waste and overflow valve.

A designates the valve casing in the form of a liquid seal trap andcomprising a valve chamber A having a top A secured thereon, while inthe bottom of the chamber is formed the valve seat A up to which leadsthe elbow shaped inlet A.

Above the valve seat in the opposite side i of the valve chamber fromthe inlet A is the outlet passage A which extends upwardly to form atrap above the valve seat and thence downwardly and inwardly into theplane of the valve chamber where it is threaded to receive the lock nutor coupler B of the waste pipe C. B is a rubber washer in lower end ofnut or coupling B and B is a wiped flange at the floor line. E is aweighted valve in the form of a ball and made of lead or other suitablemetal. This valve is made sufiiciently heavy to remain seated until thewater in the tub or other fixture reaches the desired height for washingor other purposes and so retain the water therein. Should the faucet beleft turned on, however, the increased weight of water will lift thevalve as shown in the drawing and thus establish an overflow. The usualoverflow passage which is so objectionable is thus done away with. Assoon as the ngrmal height of water in the tub, basin, &6:, is reachedthe ball will drop and retain the normal amount of water. The

shape of the casing causes a liquid seal trap to be formed at all timesagainst the en trance therethrough of sewer gas, and the valve E alsoserves at times as a valve for this purpose.

In order that the water may be discharged from the tub, basin or thelike, I provide a cage or pronged lifter F in which the ball is free torise and fall, but which will lift the ball from its seat when raised byits operating rod F. This operating rod has a handle F at its upper endwhich is within reach of the operator at the upper edge of the tub,basin and the like and the rod is secured at its lower end to the valveball cage F. Above the sage F the rod F has coarse ,threads f, whichengage internal threads a, in a chamber a formed in the top or cover AThis chamber a is closed by a cap a and suitable washers or packing a soas to prevent leakage. The rod F cannot be screwed down far enough tohold the ball or valve E to its seat, as its threaded portion willstrike the bottom of chamber a so that there is no way of leaving theball or valve locked down and thus causing an overflow. When 1t isdesired to discharge the normal contents of the fixture T, which may, asbefore stated, be a tub, basin or other recepthe rod F to rise and liftthe cage or valve lifter F, which in turn will lift the valve E from itsseat, whereupon the water will rapidly discharge through the casing.

The inlet side of the casing will be connected in any desired manner tothe bottom of the fixture T, for instance, by a pipe X, washer w, locknut or coupling 00 and the other end of pipe X is internally andexternally threaded to receive the threaded collar 8 of the strainer Sand the lock nut or coupling VV between which and the tub or fixture arethe washers U, V.

The parts are all accessible for cleaning, repair, &c.

In Fig. 2 the valve casing comprises a valve chamber A in the form of acylinder threaded at its upper and lower ends to receive the top orcover A which is the same as in Fig. 1, and the removable elbowshaped,trap forming bottom piece A clamped to the lower end of the valve casingby a lock nut or coupling A Within the conical upper end of this bottompiece A is the flanged conical washer A on which rests the valve seat Eto which is tacle, the handle F is turned so as to cause pivoted thevertically swinging valve E". This valve E is made hollow and closed bya plug or other closure E so as to receive material to give it therequired Weight to lift at any desired water pressure. Both forms ofvalves E, E have, therefore, means for holding them down on the seatuntil a certain amount of water has accumulated in the tub or receptacleT and also means for preventing their being locked down on their seats.The cage or lifter F is connected to the valve seat E at the lower endsof its prongs by lateral bends c entering notches e in the seat. Thecage or lifter F, has suflicient height above the valve to allow it torise when the cage is forced down to its lowest position so that thisconstruction broadly speaking includes means for preventing the valvefrom being locked down on its seat and this is true also of the ballvalves E both of which are free to move up wardly in their cages orlifters when the latter are forced down to their lowest positions. Therod lifts the valve seat and valve as an entirety when the contents ofthe fiX- ture T are to be discharged and so the valve has a freeindependent movement that cannot be interfered with. See the dottedlines which show the valve permitting an over flow, while the full linesshow the valve acting to retain the water in the tub or receptacle. Thedischarge passage from the casing is not integral as in Fig. 1 butconsists of a separate pipe A coupled at its upper end to a lateralnipple A at the outlet side of the casing and at its lower end connectedto the waste pipe C.

In Fig. 3 the same construction is found as in Fig. 2 except that theball valve E and the lifter F of Fig. 1 are employed and the integralvalve seat A is also employed as in Fig. 1 instead of the verticallymovable valve'seat of Fig. 2. In all of the figures the trap-like valvecasing is present, forming a water seal against the ingress of gas, andthe valve also assists in preventing the passage of gas when on its seatin addition to its functions of holding a normal amount of water in thetub or other receptacle, rising automatically to prevent an overflowwhen this normal amount is exceeded, and of being manually raised toempty the contents of the tub &c.

In Figs. 2 and 3 the wiped joint B on the waste pipe C is at thejunction of the lower beveled end of the pipe A and upper flanged end 0of the waste pipe which overlies a washer c resting on the floor. InFigs. 2 and 3 the horizontal inlet pipe X is in line with the outlet Aso that no water will remain in pipe X when the valve is manually raisedto let the water out.
